1. Data and assets must be separated into two branches & PRs. We must be careful when pushing binary blobs. Let's delay merging images for some time.
2. Data field for interests must use predefined short strings for i18n.
3. Not sure about the lab field. This doesn't have to be a one-to-one relationship. I tend to leave it under a more general tags field. In both cases, lab info must be denoted as a short string like colors, soslab, etc.

• Interests should be changed to the new arXiv tags defined in i18n files in the theme.
• Removed the images from the PR.
• Change the lab field to tags.

[furkanakkurt1335]

This should be complete.

Two things:

• Do not include photos in this PR. We will delay adding photos.
• The field 'tags' must be an array of strings. Don't use the 'affiliation' key.

Sorry, I had removed the images but they came back with another "add". Now, it should be OK.
